Hi all,I have a missfire that i'm realy struggling with.
Symptoms,I cant seem to control the revs with the accelarator pedal up to 2,000rpm.
After 2,000revs the throttle acts as normal.
Conversly when running at motorway speed,and then reducing speed to urban roads 30mph,the car seems to hold back,its hard to explain but its missing at low revs,again at under 2,000rpm.
Another symptom is if i;m at moterway speed,and need to accelerate hard to get past someone the car coughs tiwce as if its not getting enough fuel,it then accelerates as normal.
Last symptom is if i sit in the car,watch the rev counter and gently blip the throttle to say 3,500/4,000rpm,the needle of the rev counter doesent come down in a smooth motion from 4,000 to 800/9000rpm.
Any tuners on hear that can set me on the right track. Iwould be most greatfull for you'r,thoughts.I have listed what i have allready done as bellow.
New coil packs,and checked ht loom where it runs through the inlet manifold,new plugs,air filter,new injecter seals,all vaccum pipes renewed,new o ring on vaccume tree where it joins engine,cleaned and tested IAC valve,cleaned and tested MAS seems to be working as when i remove the plug it haults and then stalls,probably missed a couple if things.Oh yes tryed higher octane fuel.Honestly its got me pulling my wig off.Hope someone can relate to my problem and has an answer thanks to you all.
